The derailleurs barrel adjuster is the "goto" for the common problems. 

I’ve watched over twenty videos on derailier adjusting and I must say yours is the most clear and made the most sense. I subscribed. Thanks.

Man, thanks. FINALLY! A tutorial with a DETAILED explanation. When the others I've watched ended, I was left with more questions than I had to begin with.

Thanks, so helpful and really well explained. Had to do this on my Trek, all sorted. Cheers.

Extremely helpful, exactly what I needed to smooth out my new cable. Thanks!

Thanks Bike Teacher! Awesome vid. Well explained at a good pace. Cheers!

Thank you. Bought a used bike which I thought was a lemon. I have learn a lot from this video and other ones you've done. Very grateful

Very helpful tips. Once you memorize the barrel/rear derailleur twisting directions, it is even better to do while riding. I did it today, and my gears are swifting smoothly and fast.

Excellent advice sir.

I would like to give a big shout out to you thank you so much well explained you taught me how to use my barrel adjusters on my brakes thank you so much I didn't know what I was doing now I do thanks to you I appreciate you I definitely like your page and I hope you have more to come stay blessed

Just what I needed to get my deore xt drivetrain running better! Thank you sir.

Fixed my issues. Thank you sir!

Thank you. Just the knowledge I needed to learn. You are a good teacher, your approach too “technical teaching is so spot on” THE HOW-TOO EXAMPLE’s. Make it easier to understand & apply…

Excellent and clear advice. And no rock music accompaniment!!!

The screw analogy is great!

This is really helpful, thank you!

When the cable is new, you might need to adjust the barrel during the first days while cable "sits" properly... 🚲

So clearly explained, thank you!!

You made it very easy to understand. Thank you

The barrel adjustment video tutorial was precise, easy,, just perfect. I hungry to watch more of your well presented videos. Just Great

That explanation was very easy to follow and easy to implement. Showing the direction of viewing the barrel adjuster thus determining counterclockwise vs clockwise rotation made it easy to understand how it increases or decreases the tension. Now it will be easy to remember while riding and adjusting. Thanks.

After many videos, finally a very clear explanation!! Definitely a like and subscribe…thank you!!!

Dude you’re awesome✌️. Subscribed

So good. Thank you. 👍

I'm sure glad you put this up because, I'm too stupid to remember which way to turn that thing. Great video, thank you!

Thanks you so much

👍Thumbs up, and a red heart for the Bike Teacher King! ♥

Thank you soo much mate

Thanks, perfect!

After tips going in the right direction. Have the "Barrel adjuster grips" L (frt) and R (rear) so tried the cable adjustment into the R handle bar grip but did not seem to work all that well as the cable seemed not to adjust in tension. Is a number of small adjustments as you said that has the bike rear derailuer nearly working perfectly. 1.Sat the chain into low gear and likewise with the derailuer rear after loosening cable wire there. 2.Placed the barrel grip into low gear (6) right from back of bike. 3.Pulled wire slight tight then tightened at rear derailuer. 4.Used the two small rear screws to adjust low gear/high gear and may still have some small adjustments to make. Then tested through each change 1 L-6 H. The Low gear adjustment screw controls the low gear sprocket alignment and the high gear the same on the high side at this sprocket (Biggest Cog) you do not want the derailuer going of the sprocket into the rear wheel spokes use down-sight alignment at rear. Having the bike safely sitting in a bike stand can help with adjustments as you test out the gear changes and you will need to test multiple times before getting the right adjustments High-Mid-Low on the stand and riding. With these l and R grip adjusters you have to get use to the fact that if you go up hill when you mistakenly grip them you will change your gears accordingly which is not suitable on an incline.

all explained nicely 👌👌👌

Awesome!

good stuff oil helps well too :)

I'd loved to see a video for troubleshooting shifting on a full suspension enduro MTB. I always struggle with derailleur adjustments that "seem" to work perfect when I have the bike on the stand but the second I get it on the dirt and climb/descend the shifting goes to crap. Any tips for troubleshooting issues like that?

I like to start over like I just routed a new cable.

Quality teaching content as always. Upon going back to homebase and started to lock the cable to the rear derailleur. How much or where do you usually out the barrel adjuster on a 1x drivetrain? Thank you.

Please correct me if I am wrong. Function of adjuster near shifter: Moving anti-clockwise tightens the cable and help in shifting to bigger cogs. Moving clockwise will loosen the cable and help in shifting to smaller cogs. And this is just opposite when one is trying to do with the adjuster near the derailleur.

thank you so much, helped me with my ebike !

You saved me I’m about to go moab

I just had my deraileur dialed at the shop and it shifts up and down fine. However, I was lubing the chain and noticed the chain would drop gears when the freewheel is engaged? What could be the problem? I'm running a SRAM NX 12spd, 1X setup. Thanks

When you are unscrewing the barrel adjuster, is there some rule of thumb for when you stop, screw it back in, then loosen the pinch bolt at the end of the cable and pull the cable to take up the slack, and then go back to using the barrel adjuster? i.e. Is there some formal process for setting the cable tension, maybe with the barrel adjuster in the "center" of its range, so that you have some adjustment range in both directions?

Wish bike teacher was near me, Central Florida

Really clear - I’ve got a better idea of what the barrel adjuster actually does! Shifting sorted.

I've got a front derailleur that is operated by a grip shifter. When the cable is attached the grip shifter is very hard to turn and only turns a small amount, which is not enough to make the derailleur switch gears. If i disconnect the cable and just keep tension with my other hand, then the grip shifter works fine. As soon as the shifter cable is reattached to the front derailleur it stops working again. I can move the derailleur by manually pulling on the cable myself, but can't make the shifter pull the cable enough to make it work. Any suggestions??

Please clarify: loosening the barrel adjuster by turning it counterclockwise will increase the tension on the cable?

Should help

My chain is having issues shifting down into the smaller gears

Got a new freewheel on my bike. However, the chain skips on the 6th gear(she has six gears) when I apply load. My chain is new too. LBS says the problem would get solved once I have a few rides. Could the barrel adjuster on the handle solve the issue? LBS adjusted the one near the rear derailleur.

My front gear barrel adjuster in not going inside or outside , its just rotating on its axis.What to do?

Isn’t this what the L-screw and H-screw are for? How do I know whether to adjust the screws or the barrel adjusted? They seem like they’re both designed to correct the same problem?

Hi! What would be the «scientific » explanation on how a barrel adjuster works on inner cable tension? Thanks!

How often is it normal to increase the tension in the derailleur cable? I have a new KTM bike, and the tension in the back derailleur needs an adjustment every 2-3 hours of riding, if i shift the gears often. That means the chain starts to fall from a larger to a smaller pinion, especially while I climb a slope. Or shifting to a larger pinion gets difficult. So, is it normal that the derailleur cable needs more tension every 2-3 hours, in these condition?

I have a shifting issue on a full suspension mtb. Gears shift fine on a stand but as soon as I get out on a ride they don’t shift well at all. Typically mid range gears are the problem. Would indexing under Sag make a difference? Is that even possible? Haha

My barrel adjuster doesn't work what to do?

Hi, I'm rotating my rear barrel adjuster counter clockwise but cable is not tightening. It's not disengaged too though, so I'm not sure what's happening here.

Dumb question but Would the barrel adjuster work the same direction if it's on the rear derailleur and not on the handlebar area?

In adjusting my front derailleur's H limit, I came to a point where the barrel adjuster just wont turn either way and I can't get into the largest sprocket!! Don't know what to do now.

You are probarly not responding to comments anymore but ill give it a try I got a bike not too long ago and the gears are a little jump and it does work to unscrew the barrel adjuster to make the cable tighter but the problem is whenever i jump, do a wheelie, or simply just hit a bump it moves down aka screwing in itself. So do you have any tips to make it stop moving. And incase you wanna know the bike is a merida big nine 15. Thanks in advance

I’ve got some problem. Down shifting works perfectly fine. But shifting up doesn’t. I have to shift up to times to actually shift one gear. I have no idea why is that, I adjusted so many times so many things, but couldn’t get it to work. Could you tell me what should I do?

Seeing most bike designs these days only use a single chainring in the front and multi speed rear cassette. Won't you get extreme cross chaining across the drivetrain centerline with this design?

What is the seat post made of?

Does sitting on the bike matter 🤔

How can i fix stuck barrel adjuster even when i turn it it the cable doesnt move

When i did this the barral adjuster fell off and it did not make thr move to the bigger chainring

I dont fully understand the difference between the barrol adjustment on the shifter and on the derailleur

So the barrel adjustment is for non reactive shifts and the H and L screw adjustment is for preventing the chain from jumping out of the 1st and the last sprocket?

This bike was really easy to assemble ru-vid.comUgkxMesz3KOGEmwmvyKQfLfrRSUXLFzfVHZA and required very few adjustments out of the box. The wheels did not require any truing/adjustments. The frame had some small scratches, but nothing major.I did replace the seat though - the seat it came with was very uncomfortable. The tires need to be re-inflated every 4-5 days, but this appears to be quite common for the narrow 700x25 tires.Overall, in my opinion, this bike looks and rides like a much more expensive bike.

Hello Sir! My bike has a problem and I want to talk to you inperson. Do you have Insta or something?

Can i send you a video of my giant anthem And you see whats the problem?

I dont have a rear derailleur barrel adjuster, would that be okay?

tom morello bike repair

I accidentally backed it all the way out and it fell out.

In most of the videos about bike repair bike stand is used. A bike stand isn't very common among casual bikers and therefore maybe it would be better to demonstrate different techniques without using one.

A few more unskippable ads please

There is no barrel adjuster on my handlebars this is not helpful at all

I cannot move barrel adjuster in any direction its to tight😭😭😭😭😭😭😭 please help me
